[Pulp-list] grinder

[Jeff Ortel]

In grinder, the import (python statements) were changed to be qualified by package.  In 
the process, the src/grinder/grinder.py was renamed to src/grinder/Grinder.py because it 
obscures the "grinder" package name.  Those of you running with dev installs need to make 
sure your don't still have a src/grinder/grinder.pyc hanging around after the git pull. 
If you do, you'll see massive import errors running grinder.
